The 9! ways of arranging the letters in ZOOKEEPER have to be divided by 2! and 3! the reason being that having fixed the positions of the non-repeated letters, the O's may be arranged in 2! ways and the E's in 3! ways without making a different word:
\frac{9!}{2!3!}=30240
The answer is: 30,240 ways.

some psychologists believe that a genius should be defined as anyone having an IQ over 140. If IQ scores are normally distribute
denis23 [38]

Answer:

61,239,550

Step-by-step explanation:

We let the random variable X denote the IQ scores. This would imply that X is normal with a mean of 100 and standard deviation of 17. We proceed to determine the probability that an individual chosen at random from the population would be a genius, that is;

Pr( X>140)

The next step is to evaluate the z-score associated with the IQ score of 140 by standardizing the random variable X;

Pr(X>140)=Pr(Z>\frac{140-100}{17})=Pr(Z>2.3529)

The area to the right of 2.3529 will be the required probability. This area from the standard normal tables is 0.009314

From a population of 6,575,000,000 the number of geniuses would be;

6,575,000,000*0.009314 = 61,239,550
